After 30 months of exclusive use of Linux as my desktop environment, I decided that it was about time to refresh my knowledge of Microsoft Windows and Office. This is not about switching back to Windows. Actually, having used open-source software exclusively for such a long time, I’d say it would be quite impossible to [...]

This software, which happens to include partimage among various other utilities, has wider filesystem support and a better set of features – taking/restoring backups across the network is supported. The fact that this is [...]

Tom Newsom writes in his article: In this document I shall be showing you how you can run, for testing purposes perhaps, two versions of Slackware simultaneously.

The Red Hat Magazine included an excellent tip about how to lock out a user, if it fails to supply a valid password for a pre-defined number of login attempts.

A long time has passed since Fedora 6 was released, many of the initial bugs have been fixed, so I decided to perform an upgrade of the installation on the server that powers this web site. Everything has gone well, despite the fact that a few strange things happened during the upgrade.

pdf2email is a CUPS backend that uses GhostScript to print a document to PDF and sends the final file to the user that requested the print via email. This software is written in Python.

Today, I revised my logwatch configuration and I decided to use an external parser for the SELinux audits.

Don’t let the package name confuse you, seaudit-report is a CLI tool.
